Particle size is a key factor in understanding how pharmaceutical materials behave. Active pharmaceutical ingredients, excipients, and even the interaction between the two, can be better understood through robust particle size analysis. 

Join this webinar to discover how Malvern Panalytical’s unique combination of analytical instrumentation and CRO services can take your particle size analysis to the next level. 

Our experts in particle size analysis, Dr. Anne Virden and Dr. Paul Senior will share their inside knowledge, to show you:

  • Why you should measure particle size 
  • How particle size affects product bioavailability, uniformity, stability and processability
  • How to apply the regulatory guidance to help you decide when particle size should be considered as a ‘Critical Material Attribute’

Laser diffraction is a very popular technique for measuring particle size distributions. You’ll see how to measure particle size using laser diffraction, and how this technique generates data and how this is used to quantify critical material attributes. 

You’ll also gain new insights on method development for laser diffraction and discover strategies to ensure the best outcome in getting representative results. In particular, you’ll see how ICH guidance informs method development by focussing on concepts such as Analytical Quality by Design (AQBD) and risk assessments in method development.
